Questions about water glow injections!

These are skin boosters, commonly called water glow injections.

Although it does contain Rejuran, I am looking at it as a product that only contains hyaluronic acid, which is said to be less painful.

But my friend had it done recently, and she said that although it was less painful, Embo lasted longer than Rejuran...

First of all, since I have to go to work, it's a bit difficult for Embo to last too long.

So, I am curious about the difference in effectiveness and downtime between the regular water glow injection and Rejuran.

And what is the best thing about getting a general water glow injection?

I'd like to add some moisture, so please give me some recommendations.
